Abstract

We present new measurements of the six largest branching fractions of the [Formula Presented] using data collected in 1997 by the KTeV experiment (E832) at Fermilab. The results are [Formula Presented], [Formula Presented], [Formula Presented], [Formula Presented], [Formula Presented], and [Formula Presented], where statistical and systematic errors have been summed in quadrature. We also determine the [Formula Presented] violation parameter [Formula Presented] to be [Formula Presented]. Several of these results are not in good agreement with averages of previous measurements.
